36 V, 32-Channel (Sourcing Output), 500 µs C Series Digital Module —The NI‑9476 works with industrial logic levels and signals to connect directly to a wide array of industrial switches, transducers, and devices. Each channel is compatible with signals from 6 V to 36 V, based on the external power supply, and features transient overvoltage protection between the output channels and the backplane. You can programmatically monitor the built-in overcurrent and short-circuit protection status of each channel.
